[Charles Coldwell]

Does anyone have experience with these:

I have some of their 60-watt equivalents at home; the color is
fantastic (very close to incandescent).  I haven't done much RFI

Since these were generic ones, probably mail ordered directly from china for a really cheap price to stock this dealer's shelves, i would doubt that they had passed any type of fcc testing.
